How do you calculate the PHR of rubber compounding?
A rubber compound is a raw rubber mixed with another chemical substance that will increase the potential and performance of the rubber. A perfect example of this is vulcanisation, the chemical added is sulphur that creates crosslinks which hardens and improves the elasticity of the rubber.
